Below in conjunction with accompanying drawing the utility model is explained in further detail:
A kind of hand-held, dual-purpose hammer drill of gas leg type is assembled by long bolt 29 and long bolt nut 30 by handle body joint portion, cylinder body joint portion and head joint portion three big parts and to form.
Wherein handle body joint portion comprises on handle body 1, the handle body 1 and is connected with handgrip 20, gas-pipe bend 28 is housed is used for carrying compressed air, and control valve 21 is to open and close, regulate hammer drill running strength, the controlling organization of powerful purge by operating handle 22 controls.In handle body (1) rear end the water injection valve assembly of being made up of water filling valve body (11) and water pipe elbow (9) is housed, press water leads to petrosal foramen by the water injection valve assembly through liquid drugs injection 12 and is used for wet drilling and arranges powder often.When dry drilling, the utility model has designed the energy-saving amount adjusting valve assembly that can exchange with the water injection valve assembly, be to establish a valve body 34 in handle body 1 rear end, valve body 34 left ends are established an operating handle 32, valve 35 is packed in the valve body 34, an eccentric grove 36 is opened in termination and valve body 34 air inlet contact positions in amount adjusting valve 35 holes, directly utilizes the air-flow of handle body joint portion to realize dry type row powder, and can regulate the flow size with the depth of punchinging.
